Effects of habitat perturbation on lizard assemblages in the center-west of the Arid Chaco region, Argentina.

Several human disturbances contribute to the decrease of vertebrate species' richness and abundance, altering the processes of an ecosystem. We evaluate richness, diversity and relative abundance of species for lizard assemblages at sites with different degrees of perturbation in the center-west of the Arid Chaco region in Argentina. Between 2015 and 2018, six lizard assemblages were sampled monthly -using pitfall traps- in three areas of the Chaco, with a perturbed and an unperturbed (control) replica at each of the areas: (1) Chaco Mountain plain, (2) Chaco Mountain slope, and (3) Chaco Plains, and habitat characteristics of each study site were recorded. We captured 1446 lizards, belonging to 12 species. The perturbed area at the Chaco Mountain plain showed the greatest richness, diversity and abundance of species. In the perturbed Chaco Plains, species abundance decreased by about 50% with respect to the control site. Liolaemus chacoensis was the dominant species at all sites. Some species could be negatively affected by a total loss of arboreal strata, tree trunks and fallen leaves. Structural parameters of lizard assemblages were related to the habitat characteristics; therefore, these results provide information for the conservation and management of lands and lizard assemblages in the Arid Chaco.

O artigo discute o potencial do subprojeto Com Rio Com Mar Opinião Popular enquanto uma tecnologia social de governança participativa dos públicos atingidos pelo derramamento dos rejeitos da barragem do Fundão, que transbordou nos municípios e comunidades ribeirinhas do Estado do Espírito Santo. O artigo discute as relações entre pesquisadores e os públicos criados, associados, suportados ou estimulados pelo projeto, destacando questões metodológicas, epistemológicas e o potencial de encaixes institucionais entre sociedade civil e Estado. Argumenta-se que a Sociologia Pública e a pesquisa ação são caminhos importantes a seguir junto aos sujeitos atingidos pelo desastre. O artigo se vale de materiais produzidos nas interações com os atingidos, por meio etnográficas políticas e grupos focais durante as oficinas promovidas pelo projeto, que sugerem a necessidade de recriar a ferramenta de acordo com a realidade local.

The paper points out the potential of the Com Rio Com Mar subproject as a social technology for participatory governance of the publics affected by the Fundão dam spill, which overflowed in the municipalities and riverside communities of Espírito Santo state/Brazil. The article discusses the relationship between researchers and the public created, associated, supported or stimulated by the project, highlighting methodological and epistemological issues, and the potential for institutional fits between civil society and the State. It is argued that Public Sociology and action research are important apparatus to work with disaster-stricken subjects. The article draws on materials produced in the interactions with those affected, through political ethnographic and focus groups during the workshops promoted by the project, which suggest the need to recreate the tool according to local reality.

El artículo analiza el potencial del subproyecto Com Rio Com Mar Opinião Popular como una tecnología social para la gobernanza participativa del público afectado por el derrame de la presa Fundão, que se desbordó en los municipios y las comunidades ribereñas del estado de Espírito Santo. El artículo analiza las relaciones entre los investigadores y el público creado, asociado, apoyado o estimulado por el proyecto, destacando cuestiones metodológicas, epistemológicas y el potencial de encaje institucional entre la sociedad civil y el Estado. Se argumenta que la Sociología Pública y la investigación de acción son vías importantes a seguir con los sujetos afectados por desastres. El artículo se basa en materiales producidos en la interacción con los afectados a través de grupos etnográficos y grupos focales durante los talleres promovidos por el proyecto, que sugieren la necesidad de recrear la herramienta de acuerdo con la realidad local.

L'article traite du potentiel du sous-projet Comriocommar Opinião Popular en tant que technologie sociale de gouvernance participative des publics touchés par le déversement des rebuts du barrage du Fundão, qui a débordé dans les communes et les communautés riveraines de l'Etat de l'Esprit Saint. L'article traite des relations entre les chercheurs et les publics créés, associés, soutenus ou stimulés par le projet, mettant en évidence les questions méthodologiques, épistémologiques et le potentiel de liens institutionnels entre société civile et Etat. On fait valoir que la sociologie publique et la recherche d'action sont des voies importantes à suivre auprès des sujets frappés par le désastre. L'article s'appuie sur des matériaux produits dans les interactions avec les personnes touchées, par des politiques ethnographiques et groupes focaux au cours des ateliers promus par le projet, qui suggèrent la nécessité de recréer l'outil selon la réalité locale.
